Where are we as act 2 begins, what is the situation at sea? What happened to the Turkish fleet?

A terrible storm has struck Cyprus, just as the Turks were about to approach. The Turkish attack may have been quelled, but it also bodes badly for Othello's ship. A messenger enters, and confirms that the Turkish fleet was broken apart by the storm, and that Cassio has arrived, though Othello is still at sea. They spot a ship coming forth; but Iago, Desdemona, and Emilia are on it, not Othello.
